Patent JP-H11266407-A (JP)
Title: Tuner
Inventor: ITAYA TAKESHI
IPC: H04N5/44
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To suppress disturbance of a peaking circuit in a reception circuit block not in operation onto a reception circuit block in operation in the case of receiving a program while dividing a frequency band into a plurality of reception circuit blocks. SOLUTION: The tuner 31 uses a band changeover switched 35 to select an output of a power supply 34 thereby selectively activating a UHF band block 32 or a VHF band block 33. A loss correction circuit 44 (45) is a parallel resonance circuit consisting of a coil 46 (56) and a capacitor 47 (57) and acts like a peaking circuit to correct a loss within a reception frequency band. When the VHF band block 33 is in operation, the loss correction circuit 45 in the UHF band block 32 does not act like a peaking circuit because a switching circuit 48 is open so as to control extraction of a resonance frequency component with a resonance frequency causing image disturbance to the reception channel of the VHF band block 33.

Title: Method of flattening process
Inventor: MORIUCHI NOBORU
IPC: H01L21/30
Filed: 1988-03-25
Abstract: PURPOSE:To obtain a flat surface with few level difference, by exposing photosensitive material by a light beam having exposure intensity distribution changing continuously according to the height of the surface and by removing it partially according to the exposure distribution. CONSTITUTION:The surface of a base layer 12 is coated with photoresist 13. The resist 13 is exposed by using a photomask 14. The exposure is processed by an exposure distribution which changes continuously according to the height of the base layer 12, a surface to be exposed. Then the resist 13 is developed. The resist 13 is partially removed according to the exposure distribution given by an exposure process. By this a flat surface is obtained with the resist 13 left so as to get rid of a difference of elevation h. When etched back, the surface of the base layer 12 is removed off uniformly together with the remaining resist 13, thereby obtaining a flat surface of the base layer 12 with no difference of height.

IPC: H03H3/08
Filed: 1978-06-12
Abstract: PURPOSE:To increase greatly the formation precision of a transducer, upon which curvature of a wafer due to the roughening of the reverse depends, by roughening the reverse after forming the transducer on the top of the piezoelectric wafer.

Title: Josephson direct coupling type not circuit
Inventor: NAGASAWA SHUICHI
IPC: H01L39/22
Filed: 1985-04-04
Abstract: PURPOSE:To provide a wide operating region of a bias current by connecting the 2nd bias current input terminal and the 3rd bias current input terminal among the 1st-4th bias current input terminals and connecting the 4th bias current input terminal to common. CONSTITUTION:When a data signal '1' is inputted to a terminal I1 while a bias current is fed from a terminal B1, Josephson junctions 6, 110, 111 are switched into the voltage state and a high impedance state is attained. Thus, most of the bias current flows to common through a load resistor 2. Since no bias current flows to Josephson junctions 115, 116, even when a timing signal is inputted to a terminal I2, no current flows to an output resistor 4 being an output line and a complement signal '0' of the data signal '1' is obtained. It is required to give a high impedance for the Josephson junction so as to provide a high operating margin of the bias current and a high gain characteristic for the NOT circuit. The condition is obtained by deciding the load resistor 2 and an output resistor 4.
